With the rapid improvement of China’s socio-economic level, the importance of ecological environmental protection has become increasingly important. As a major factor affecting ecological environmental protection, carbon emissions have received high attention. At the same time, various tasks for energy conservation and emission reduction have entered a period of rapid development. In China’s construction industry, green buildings are the main measures for energy conservation and emission reduction. The use of green buildings to achieve water, material, and energy conservation can not only ensure environmental benefits, but also improve ecological benefits. In order to further improve the environmental benefits of green buildings from the perspective of carbon emissions, it is also necessary to conduct a specific analysis combining the development advantages and environmental benefits of green buildings.

The application of green low-carbon building technology in the construction industry has gradually been promoted. The construction industry, as an energy-intensive and consumable industry, can reduce the energy and resource consumption of the industry with the combination of green and low-carbon building technology. This also indicates that the future construction industry will realize the development of low-carbon buildings and achieve sustainable development of the construction industry.

To address challenges posed by waste tires and greenhouse gas emissions associated with ordinary Portland cement, exploring eco-friendly construction materials is critical for sustainability. This study examines the workability and mechanical properties of straight steel fiber-reinforced rubberized geopolymer concrete (SFRRGC), where rubber powder is derived from recycled waste tires. The experimental variables included rubber powder (RP) content (0%, 6%, 12%, and 20% by volume of fine aggregate) and steel fiber (SF) content (0%, 0.5%, 1.0%, and 1.5% by volume). The results show that incorporating RP and SFs reduced the workability of SFRRGC but increased its peak strain. Specifically, RP addition decreased the elastic modulus, compressive strength, and toughness; increasing the SF content enhanced energy dissipation, while the effects of SF and RP contents on Poisson’s ratio were negligible. The specimens showed that a higher RP content would weaken the crack-bridging effect of SF. For example, specimens with 1.0% SF and 6% RP achieved 49.56 MPa compressive strength and 4.04 × 10⁻³ maximum peak strain; those with 0.5% SF and 20% RP had 118.40 J compressive toughness, which was 5.53% lower than that of the reference specimens (125.33 J). Furthermore, a constitutive model for SFRRGC was proposed, and its theoretical curves aligned well with the experimental results. This proposed model can reliably predict the stress–strain curves of geopolymer concrete with different SF and RP mixture proportions.

The continuous development of virtual reality technology has improved the production efficiency of various industries. The application of virtual reality technology in the protection and maintenance of historical buildings can provide relevant practitioners with new work directions. Based on previous work experience, this article summarizes the content of historical building protection based on virtual reality technology. Moreover, the author also discusses the protection and maintenance of historical buildings based on virtual reality technology from the following four aspects. It includes the maintenance characteristics, the specific conditions of the project, reasonable maintenance plans formulation, and three-dimensional virtual environment modeling.
